## DSI-2 Reviews in United States

### ***** "Five stars amazing product"
10 out digitally processed channels with 6 analog input, simple yet very effective. It’s able to  Build a very complex system. Being able to tune all that from your phone, wow. App works great for iPhone 12 and XR. Using this for a portable Bluetooth speaker and to the person asking if you can use some regular Bluetooth adapter, I don’t know but if you use the CORRECT one the unit works great! Overpriced or not, it’s worth it for it to work correctly. Issue with people trying to build a nice sounding system is being cheap. Just my 2 cents.

### ***-- "Help?"
Does anyone know if you can use any bluetooth 4.0 usb dongle? instead of buying their overpriced one?
-- Trevino43, 2019-07-15

### *---- "It doesn’t let me connect to the DSI-2 on iPhone X"
New update for i phone needed ASAP
-- jtije60, 2019-03-08

### *---- "App doesn’t work for IOS 12.1.4"
I have an iPhone XS Max and I can’t use this app to tune my DSI-2. I tried to connect via an android device and it worked fine. I guess the app needs an update to work with the latest IOS update or something of that sort.

### ***** "DSP tune and Steam music"
Awesome app to steam music with Bluetooth 4.0 as well as tuning on the fly via cellphone. Master volume control and more. No head unit needed. Phone, DSI-2, amps to speakers and you are good to go. Easy to learn and use. Huge improvement on audio quality and performance.
